Our sources have said that GLBenchmark is heavily iOS optimised and that Tegra 3 final hardware should be close or slightly better than SGX 543 MP2, not losing by that much.

All in all, Tegra 3 should at least win some, and lose some against SGX 543 MP2 and iPad 2 / iPhone 4S chips, and not lose by such a high margin. We guess we should wait and see as Transformer Prime benchmarks should go live in the next two weeks, if not earlier.
